BUTTON sraucn nnn.

Application fiied November 18, 1522. Serial No. 601,849.

To all whom it may concern:

Be'it known that I, LEW AnN'rz, a citizen of the United States, and aresident of Des Moines, in the county of Polk and State of lowa,haveinvented a certain new and use ful Button Structure, of which thefollowingis a specification.-

The object of my invention is to providev a button structure of simple,durable, and comparatively inexpensive construction.

More particuhirly, my invention relates to a button structure, whichmaybe easily 5e cured to any suitable material and which, when once placedin position, will become permanently locked against undesired removal.

More particularly, my invention relates to a two-part button structurewhich when securely locked together, there will be no rota- 20 tion ofthe parts except in one predetermined position.

Still another object is to provide a peculiar type of button in whichthe parts may be quickly separated for removing it from the material towhich it is fastened.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claim, and illustrated in theaccompanying drawings, in which:

Figure 1 is a top plan view of the button.

Figure 2 is an inverted plan view of the front member of the button.

Figure 3 is a top view of the back mem her. 7 v Figure 4: is a sideelevation of the parts or the button connected together.

Figure 5 is a sectional view taken on line 5-5 showing the buttonconnected to cloth.

Figure 6 is a sectional viewof a slightly modified form of button; and

Figure 7 is a view similar to Figure 42 with the back member having asmooth face.

In the accompanying drawings, I have 50 used the reference numeral 10 toindicate generally, the front member and 11 to indi- V 55, hub or thelike portion 12. The member 10 is-provided with a central .screw threaded opening 13 and the member 11 'is provided with a central screwthreaded mendher 14:. The screw threaded'members 13 and 14 are inalignment'with each other andreceive the screw 15.

On the adjacent faces of the front and back members =10 and 11, Iprovide coacting engaging parts 16 and 17. The coacting engaging parts16 and 17 are. preferably teeth, which may engage .the cloth on eachside. The coacting engaging parts are radially spaoed from the screwthreaded openings in the front and back member so as to form a recesswithin the ring termed by the teeth or coacting parts. The screw extends through the cloth 18 and connects the front and back members 10and 1]. together.

It will be seen that the member 11 may be rotated in the directionindicated by the arrow 19 for looking it in position. The fact that thecoacting teeth 16 and 17 will engage on each side of the cloth, willprevent any rotation of the back 11 in the direction opposite from thatshown by the arrow 19.

When it is desired to remove the button, all that is necessary is tounscrew the screw 15. My button is very practical for use on overcoatsand other heavy materials, but will work successfully on all kinds ofcloth.

In Figure 6 of the drawings, I have shown a slightly modified form ofbutton in which the front member is composed of the two parts 20 and 21.The part 20 may be made of shell or any other suitable material, and isconnected to the part 21 by having inturned flanges 22 on the member 21,which extend into a groove 23 formed in the member 20.

The parts just described are clearly shown in Figure (3 of the drawings.

The part'21 is provided with a screw threaded stem. 24. A back member25, similar in construction to the member 11 is used for engaging thestem 24.. The part 21 is provided with teeth 16 which are radiallyspaced from the stem or screw threaded member 2 1. Thecoactmg parts Forengaging the cloth 18, as shown, in Figure 6, similar in construction tothose shown in the rest of the drawings.

In the form of invention shown in Figure 6, it is impossible to removethe back member when once placed in position, with out tearing thematerial on which the button is fastened. In Figure 7, I have shown theback member 11 with a smooth face, thereby providing a button havingonly one part provided with teeth or the like to engage the cloth. Thesmooth face may be put on the front member and roughened part on theback member if desired. This type can be removed from the cloth if de-Isired without any injury to the cloth. It Will be understood that theroughened parts may be made in various sizes for accom plishing theresult desired.

It will be seen that my button may be easily and quickly fastened tocloth and, in View of the fact that it comprises a front and backmember, will remain in position Without danger of being completely tornaway fromthe cloth.

Some changes may be made in the con struction and arrangement of thevarious parts of my invention, without departing from the real spiritand purpose of my invention and it is my intention to cover by my claim,any modified forms of structure or use of mechanical equivalents, whichmay be reasonably included within its scope.

- I claim as my invention:

A button structure of the class described including a front and a backmember, said front-member having a screw threaded stem thereon, teethformed on one of the faces of said front member and spaced radially fromsaid stem, said teeth extendingupwardly from the face of the men'iber onwhich they are mounted for forming a recess, said back member having ascrew threaded opening therein for receiving said stem, teeth formed onone face of the backinember for wanting with the teeth on thefrontmember,-said teeth being spaced radially from said opening andextending upwardly from the face of the member on which they are mountedfor forming a recess, the material on which the button is fastened beiuengaged by said teeth at a point spaced from the point where thestcmextends through the material as and for the purposes stated.
